Error description

• API backups can fail in certain conditions where there are
  multiple backups running concurrently.  The faulting module is
  tsmapi64.dll. Windows event log entries will look similar to the
   following:

  Support/Customer diagnostics
  An API trace will show that the Spectrum Protect API called the
  destructor of DccPolicyEnforcer class although the constructor
  class was not called at all.
  The DccPolicyEnforcer class was not constructed since there is
  an issue during creation of global mutex:
  
  {Timestamp} [005496] [12732] : ..\..\common\winnt\psthread.cpp(
  527): Create mutex failed; reason 5.
  {Timestamp} [005496] [12732] : ..\..\common\vs\gtex.cpp( 307):
  gtex mutex [Global\FmDbNodeProxyLock] failed to create global
  named mutex rc = -1
